[v2] net/netvsc: ignore NVS_TYPE_TXTBL_NOTE while executing a sync command
Checks
Commit Message
From: Long Li <longli@microsoft.com>
On netvsc initialization, the host VSP may send a NVS_TYPE_TXTBL_NOTE
packet while executing a VSP command synchronously.
Instead of returning an error, ignore this packet as we don't use it for
DPDK.
